Offer's most recent work, The Challenge of Affluence: Self-Control and Well-Being in the United States and Britain since 1950, represents to some extent a challenge to Neoclassical economics. Through it he argues that "well-being" has in fact lagged behind the increasing affluence of western societies: that "affluence breeds impatience, and impatience undermines well-being...the paradox of affluence and its challenge is that the flow of new rewards can undermine the capacity to enjoy them."[2] The central concepts are therefore future discount, bounded rationality, and myopia.
